Resettable Safety Shield For Medical Needles - Patent 7179244


BACKGROUND1. Technical FieldThe present disclosure generally relates to safety shields for medical needles, and more particularly, to resettable safety shields that protect a needle point of a medical needle.2. Description of the Related ArtProblems associated with inadvertent needle sticks are well known in the art of blood sampling, percutaneous medication injection and other medical procedures involving use of medical needles. Significant attention has been focused on needlestick problems due to the contemporary sensitivity of exposure to AIDS, Hepatitis and other serious blood-borne pathogen exposures.Procedures for removing a needle from a patient commonly require a technician to use one hand to place pressure at the wound site where the needle is being withdrawn, while removing the needle device with the other hand.

Providing adequate care while following safety procedures is often compounded by the patient's physical condition and mental state, such as in burnunits and psychiatric wards. Under such conditions, it is difficult to properly dispose of a used needle while caring for a patient.The widespread knowledge and history associated with needle care and disposal problems have resulted in numerous devices for preventing accidental needle sticks. Problems of current safety devices include difficulty of use and high cost due totheir complexity and number of parts.Other known devices employ sheaths that are spring activated, telescoping, pivoting, etc. These devices, however, may disadvantageously misfire or be cumbersome to activate. Further drawbacks of current devices include high manufactu
